We have made a file which provides mappings between iRefIndex identifiers and popular external identifiers. The file is a tab delimited text file and the first row starting with the "#" provides the column headers.

File download location:

The column descriptions:

Column number Column name Description
1 db Source of the external identifier (e.g. UniProt, RefSeq)
2 acc The external identifier (e.g. Q4U9M9)
3 entrezGeneid Entrez gene id. This is provided only for RefSeq identifiers
4 irogid Integer version redundant group identifier(e.g. 3156116, current maximum value=, this is a MySQL ).
5 rogid String version of the redundant object group (64 bit version of the hash digest of primary amino acid sequence with the NSBI taxonomy identifier appended at the end)
6 icrogid Integer version of the canonical(1) redundant object group (A selected irogid to represent the canonical group)
7 crogid String version of the canonical(1) redundant object group (A selected rogid to represent the canonical group)
